Background

Since fifteen, our army began to attach importance to the development of various protective capabilities of military vehicles, and developed the research of passenger restraint systems of special vehicles in sequence, wherein the energy isolation and buffering functions of protective devices became the key and hot spot in the research. Military vehicle operating mode has considerable difference with the civil car, and non-road pavement road is many, and at daily in-process of traveling, need prevent that energy cuts off device core spare part from producing fatigue, so need more safety mechanism come to deal with the impact that daily vehicle jolted and cause to can in time break away from when the detonation comes, cut off buffer by the core energy and carry out energy and cut off and cushion. When the explosive explodes instantaneously, the huge transient impact force enables the vehicle body to generate a local effect for the first time, the living space of the passenger is quickly extruded, then the vehicle has an overall effect, the vehicle is flushed away from the ground by the huge impact force, and then a falling effect and a subsequent effect are generated.

At present, the research of the explosion protection key technology in China is not completely mature. In the light of the above situation, relevant devices are being researched abroad, and at present, the belt type is mainly hung on a vehicle body and the spring and damper, the belt type is not in contact with the ground to reduce the damage of explosion impact, and the spring and damper attenuate the energy of the explosion impact through the quick response of the damper. However, the reliability of both is not good enough, and the protection effect against impact is unstable.

Description of reference numerals:

the energy-saving device comprises a vertical column 1, a spring retainer 2, a spring plate 3, a butt joint part 4, an upper fastener 5, a sliding sleeve 6, an energy partition box 7, a steel pin 8, a partition steel wire 9, a lower fastener 10 and a limiting piece 11.

Detailed Description

The present invention is described in further detail below with reference to the attached drawing figures.

An object of the application is to provide a rope formula energy cuts off buffer, and application safety mechanism cuts off buffer with the energy and comes from the external big impact of the axial transient state of stand along the stand, through fixed platform power, effectively reduces the impact that passes to personnel and equipment to protection personnel and equipment exempt from to receive the harm.

Coupling mechanism includes stand 1, last fastener 5, lower fastener 10 and interfacing part 4, interfacing part 4 is T type structure, and bottom accessible bolt links to each other with the external world, and the top can disect insertion go up fastener 5 and lower fastener 10 and reserve the notch, through bolt or bolt-up, needs protective apparatus or personnel to be fixed in on the stand 1 through all the other devices.

The safety protection mechanism is arranged in the connecting mechanism and comprises a spring collar 2, an elastic sheet 3 and a sliding sleeve 6, wherein two ends of the elastic sheet 3 are arranged at the bottom of an inner ring of the upper fastener 5, and a notch is reserved at the bottom of the inner ring, the upper surface of the elastic sheet is in contact with the sliding sleeve 6 and penetrates through an opening in the middle of the upright post 1, so that the axial displacement along the upright post 1 is limited, and the weight carried by the upright post is born during daily running.

The sliding sleeve 6 is respectively arranged in the upper fastener 5 and the lower fastener 10 to ensure the smoothness of the axial sliding of the upright post 1, and the upper end surface of the sliding sleeve is contacted with the spring retainer ring 2. And the spring retainer ring 2 is arranged at the upper end of the sliding sleeve 6 and is respectively embedded in the reserved grooves of the upper fastener 5 and the lower fastener 10 to fix the sliding sleeve 6.

When facing to come from stand 1 axial impact, the energy spreads into through interfacing part 4, last fastener 5 and lower fastener 10 fast, when conducting to shell fragment 3, because shell fragment 3 can carry out slight deformation and fatigue-resistant characteristics, can relapse slight bounce in last fastener 5 and lower fastener 10, plays buffering and stable effect.

The energy partition buffering mechanism comprises an energy partition box 7, a steel pin 8 and a partition steel wire 9, wherein the energy partition box 7 is arranged on the upright post 1 through a bolt, and the partition steel wire is wound between reserved notches of the upper fastener 5 and the lower fastener 10 and is always fixed with the butt joint piece 4, the upper fastener 5 and the lower fastener 10 when facing impact; the steel pin 8 is arranged in the energy partition box 7 and is directly assembled with the partition steel wire 9.

When the energy partition buffering mechanism encounters large transient impact along the axial direction of the stand column 1, when the impact exceeds the limit stress of the elastic sheet 3, the elastic sheet 3 can be broken fragile, the stand column 1 is in a suspended state and only keeps a main force transmission relation with the partition steel wire 9, and then the energy partition box 7 and the steel pin 8 are driven to start moving, because the two ends of the partition steel wire 9 are fixed on the upper fastener 5 and the lower fastener 10, the upper fastener 5 and the lower fastener 10 are relatively fixed with the butt-joint piece 4, the energy partition box 7 and the steel pin 8 can rapidly and repeatedly bend and recover the partition steel wire 9, and therefore huge impact energy is partitioned.

The number and size of the steel pins 8 and the partition steel wires 9 can be changed according to the requirements of required protective performance, starting load and stability. The initial distance between the energy partition box 7 of the energy partition buffering mechanism and the upper fastener 5 in the connecting mechanism is adjusted according to protection requirements, so that the practicability and the adaptability of the mechanism are improved.

As shown in fig. 5, the rope type energy partition buffering device is schematically installed when being applied to a protective seat, and the energy partition buffering mechanism plays a role in the overall effect and the drop effect, so that the energy of transient large impact is partitioned and buffered, and the safety of personnel and equipment is further guaranteed.
